Design of Ductile Iron Pipe Systems
To ensure a reliable, low maintenance infrastructure capable of withstanding the test of time, proper initial design is essential. The basis of the design standard for ductile iron pipe...

Sliplining with Ductile Iron Pipe
The utilization of Ductile Iron Pipe (DIP) as an alternative to be considered for sliplining rehabilitation of sewer pipelines is evaluated. A recent experience in sliplining a failing...

Effects of Ground Failure on Ductile Iron Pipe
The design studies and procedures outlined in this paper for pipelines that must cross earthquake fault zones are also applicable to similar ground disturbances resulting from landslides,...

The Nebraska Chemigation Cat?1987 in Review
The Nebraska Chemigation Act was signed into law in April of 1986 with requirements effective January 1, 1987. The Act is one of the most comprehensive pieces of chemigation legislation...

Chemigation Backflow Prevention Assemblies
Chemigation with sprinkler irrigation systems is widely used throughout the United States. One potential environmental hazard of this practice is the point source water contamination due...

Advanced Chemigation Systems for Environmental Safety and Groundwater Protection
A multifunction irrigation system has been developed which utilizes a separate dynamic in-canopy nozzle system for chemical application. Testing the system with a lithium tracer on four...

Potassium Fertigation in Drip Irrigated Peppers in Puerto Rico
Three potassium fertigation rates (T1 = 100%, T2 = 60%, T3 = 30%) via trickle irrigation, fertilization rates (T4 = 100%, S1 = 100%, S2 = 50%, S3 = 0.0) and nonfertilization (T5 = 0.0)...

Variability of Copper in the International Reach of the Similkameen River, British Columbia
All total copper concentrations measured in soft water during spring freshets were above the Canadian Water Quality Guidelines. Approximately 57% of all 108 observations over the three-year...

Adsorption, Desorption and Transport of Pesticides in Groundwater: A Critical Review
Adsorption and desorption are major mechanisms affecting the transport and fate of pesticides in groundwater. Equilibrium, chemical nonequilibrium and physical nonequilibrium adsorption...

Riverbank Instability Due to Bed Degradation
Degradation lowers the bed of an alluvial channel over a long reach. This has the effect of increasing the bank heights and angles, which decreases the stability of the banks with respect...

Generation of Native FE in Lunar Soil
Electron Spin Resonance (ESR) studies on lunar samples produced some unexpected results which led to recognition of the presence of abundant single-domain Fe^o...

Carbonyl Extraction of Lunar and Asteroidal Metals
The century-old Mond process for carbonyl extraction of metals from ore shows great promise as an efficient, low energy scheme for producing high-purity Fe, Ni, Cr, Mn, and Co from lunar...

Lunar Oxygen Production from Ilmenite
Carbotek has developed a process for oxygen production from ilmenite-rich lunar deposits to support lunar base operations and large-volume propulsion needs. The reduction of iron oxide...

Oxygen Production for a Future Lunar Base
This paper discusses various ways for providing oxygen for a lunar base. Currently, there are three methods available which are technologically possible. One of these is the use of chemical...

Out of the Mainstream
By treating only part of the wastewater stream, a biological/chemical phosphorus removal system also reduces chemical costs and sludge production. The system consists of two 60 ft dia...

Program to Reduce Deicing Chemical Usage
Over the years (since about 1948), the dependency on deicing chemicals has been increased to provide 'bare pavement' for safe and efficient winter transportation....

Recovery Efficiency From Single-Well Injection/Recovery Tests in a Limestone Aquifer of High Secondary Porosity
An analytical advection-diffusion model was developed to assess the feasibility of injecting and recovering water in a limestone aquifer of high secondary porosity. The model was calibrated...

Artificial Recharge of Ground Water
A need for international and interdisciplinary technology transfer on the subject of artificial recharge resulted in the American Society of Civil Engineers' (ASCE) Irrigation...

The Ozone Defense
Ozone is a molecule containing three oxygen atoms. When bubbled through drinking water, the third atom in ozone is attracted away by other molecules, a process called oxidation. This process...

Managing Dioxin
Dioxins, among the most toxic compounds known to man, are by-products from production of other chemical products. There are currently about 5000 metric tons of dioxin-containing wastes...
